Ingredients You’ll Need

• 1 ½ cups all-purpose flour: This forms the base of the crust and provides structure to the bars.
• ½ cup granulated sugar: This adds sweetness to the crust and the custard.
• ¼ teaspoon salt: This enhances the flavors of both the crust and the filling.
• ½ cup unsalted butter: Melted butter creates a rich and flaky crust.
• 2 cups chopped rhubarb: Fresh rhubarb gives the bars their tangy flavor. Make sure to chop them into small pieces for even cooking.
• 3 large eggs: Eggs help set the custard filling, giving it a creamy texture.
• 1 cup heavy cream: This adds richness and smoothness to the custard.
• 1 teaspoon vanilla extract: Vanilla enhances the flavor of the custard.
• ½ cup brown sugar: This adds depth and a slight caramel flavor to the custard filling.

How to Make

1. Preheat your oven: Start by preheating your oven to 350°F (175°C). This ensures that your bars will bake evenly and achieve the perfect golden color.
2. Prepare the crust: In a mixing bowl, combine 1 ½ cups of all-purpose flour, ½ cup of granulated sugar, and ¼ teaspoon salt. Then, pour in ½ cup of melted butter and mix until you have a crumbly mixture. Press this mixture into the bottom of a greased 9×9-inch baking pan, ensuring an even layer.
3. Bake the crust: Place the crust in the preheated oven and bake for about 15 minutes, or until lightly golden. This pre-baking step allows the crust to set before adding the custard filling.
4. Prepare the custard: While the crust is baking, whisk together 3 large eggs, 1 cup of heavy cream, 1 teaspoon of vanilla extract, and ½ cup of brown sugar in a separate bowl until smooth. The mixture should be creamy and well-combined.
5. Add the rhubarb: Once the crust is out of the oven, sprinkle 2 cups of chopped rhubarb evenly over the crust. Then, pour the egg and cream mixture over the rhubarb, ensuring it is evenly distributed.
6. Bake the bars: Return the pan to the oven and bake for an additional 25 to 30 minutes. You’ll want the custard to be set but still slightly jiggly in the center. It will firm up as it cools.
7. Cool and slice: Once baked, remove the bars from the oven and allow them to cool to room temperature. For best results, refrigerate them for a couple of hours before slicing. When ready to serve, cut into squares or rectangles.

Variations & Substitutions

Strawberry Rhubarb Variation: You can substitute half of the rhubarb with strawberries for a sweet twist on the classic recipe. The strawberries will infuse a sweet flavor that balances out the tartness of the rhubarb. Simply chop the strawberries and toss them in before adding the custard layer.

Gluten-Free Version: For those who are gluten intolerant, replace all-purpose flour with a gluten-free flour blend. Many well-made blends behave similarly to traditional flour and will give you the proper texture. Just make sure that the blend you choose contains xanthan gum or add it separately to help achieve the right consistency in the crust.

Vegan Custard Bars: If you’re looking for a plant-based version, substitute the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water equals 1 egg), and use coconut cream instead of heavy cream for a rich texture. The sweetener can also be switched to maple syrup for a lovely flavor profile that complements the rhubarb.

Common Mistakes to Avoid

One common mistake is overbaking the custard. Overbaking will lead to a rubbery texture. Always keep an eye on the baking time and check for doneness early. Another error is not properly chopping the rhubarb. Large chunks can remain raw in the custard, impacting the overall texture. Make sure to chop them into small, even pieces. Lastly, allowing the bars to cool completely before slicing is crucial. Cutting them too early can result in a messy presentation.

Storage, Freezing & Reheating Tips

These bars can be stored in an airtight container in the refrigerator for up to five days. To freeze, cut the bars into portions, wrap each piece in plastic wrap and then place them in a freezer-safe bag. They can last up to three months in the freezer. To reheat, simply thaw in the refrigerator overnight and warm gently in the oven at 300°F (150°C) for about 10 minutes or until warmed through.

Frequently Asked Questions

Can I use frozen rhubarb?
Yes, frozen rhubarb can be used. Just make sure to thaw it first and drain any excess moisture to prevent the bars from becoming soggy.

How do I know when the custard is done?
The custard is done when it is set but still slightly jiggly in the center. It will firm up as it cools, so avoid overbaking to retain a creamy texture.

Can I add other fruits?
Absolutely! You can experiment with other fruits, such as blueberries or blackberries, to mix in with the rhubarb, giving a unique twist to the bars.

Why did my custard crack?
Cracking can happen if the custard is baked at too high a temperature. Ensure your oven isn’t too hot and consider using a water bath for more gentle, even baking.

Do I have to use heavy cream?
While heavy cream adds richness, you can substitute it with half-and-half or whole milk for a lighter version. Just note that the texture will be slightly different.
